It sounds like a good idea-to have a monolithic coating that seals against all leaks but the usual homeowner solutions don't cut it. I have heard those that apply the specialized rubber roof coatings have success but when the products start approaching the cost of a total new EPDM skin, I think, what's the point? You could apply the Kool Seal product that is made for EPDM as it will lower temperature but that doesn't get all of those roof through holes sealed.westend wrote:
I'd suggest you remove the failed sealant and replace it with Dicor lap sealant or Eternabond tape. BTW, there is no good use for silicone based sealers on an RV.
You could try a fabric-friendly rust/stain remover on the interior. Don't know how successful that will be but probably worth a try if the ceiling only has a few spots.
So you are suggesting only Dicor or Eternabond and no Kool Seal?
If you used a latex caulk on the roof, you now have another layer of sealant to remove.
